On Start the Week Lisa Jardine talks to the artist Gavin Turk about the construction of artistic myth and the question of authorship and authenticity. The rare book dealer Rick Gekoski searches for lost treasures amid tales of theft, forgery and destruction, while the curator Paul Roberts reveals the life and culture preserved in the volcanic devastation of Pompeii and Herculaneum. The everyday object - a table - is at the centre of Tanya Ronder's new play of belonging, identity and inheritance.
